Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   43801   clinical trials with a EudraCT protocol, of which   7259   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    4. Male or female 18 to 75 years of age, inclusive.
    5. Diagnosis of moderate to severe active UC made at least 3 months before the screening visit. The diagnosis of UC must have been confirmed by endoscopy, with a minimal extent of 15 cm from anal margin and histology (i.e., histopathology report available in the patient’s file); however, a biopsy for a local histopathology assessment at screening can substitute this requirement.
    6. Previous or current biologic therapy for UC with documented history of a primary non clinical response or, a secondary loss of response to at
    least 1 of the following agents used at a dose and regimens approved for the treatment of UC for sufficient time (including approved biosimilars):
    • Anti-TNF-α agents
    • Vedolizumab
    • Ustekinumab
    Or to 1 of the following investigational biologic agents (i.e. not yet approved in UC) used at a therapeutical dose (in such situations, prescreening
    discussions with the Medical Monitor of the study will allow to define if the conditions of non-response are met) :
    •Other biologic …
    7. Patient currently receiving 1 or more of the following medication(s) for UC is eligible, provided that he/she has been receiving such treatment(s) for at least 4 weeks and with no change in dose or frequency in the 2 weeks prior to screening:
    a. Oral aminosalicylates anticipating that the dose at screening has to be maintained until Week 10.
    b. Prednisone (stable doses ≤ 20 mg/day) or equivalent, budesonide MMX (stable doses ≤ 9 mg/day), or beclomethasone dipropionate (stable doses ≤ 5 mg/day), anticipating that these stable doses have to be maintained until Week 10.
    If these medications have recently been stopped, the treatment cessation must have occurred at least 2 weeks prior to screening
    8. Patients who have been previously receiving anti-TNF-α therapy or vedolizumab or ustekinumab must have discontinued this therapy ≥ 8 weeks before the date of baseline endoscopy or ≥ 5 half-lives before the date of baseline endoscopy in case of investigational biologics agents.
    9. For patients with UC >8 years, results of a surveillance colonoscopy conducted within 2 years prior to screening are required to rule out dysplasia. This full colonoscopy might be done at screening instead of the procto-sigmoidoscopy to fulfill this requirement.
    10. Either chest x-ray within the 3 months prior to screening and/or a negative quantiFERON TB Gold In Tube test according to local guidelines and standard of care to exclude active or latent TB infection.
    E.4Principal exclusion criteria
    1. Stoma, proctocolectomy, or subtotal colectomy
    2. Physician judgment that patient is likely to require any surgery for UC during the study duration, or double-blind phase duration at least
    3. Evidence of fulminant colitis, toxic megacolon, or perforation
    4. Current or recent (within 4 weeks prior to screening) hospitalization for UC care and/or treatment with IV steroids
    5. The following laboratory results at screening:
    a. Elevation at screening of aspartate aminotransferase (AST), alanine aminotransferase (ALT) > 3 × the upper limit of normal (ULN) or total bilirubin > 2 × ULN (unless due to Gilbert’s disease) or evidence of chronic liver disease
    b. Platelet count < 100,000/mm3
    c. Hemoglobin (Hgb) < 8.5 g/dL
    d. Neutrophils < 1500/mm3
    e. Lymphocytes < 800/mm3
    f. Absolute white blood cell (WBC) count < 3000/mm3
    6. Crohn’s disease or indeterminate colitis or any other diagnosis not consisting with UC
    7. History or evidence of incompletely resected colonic dysplasia or unconventional lesion at risk of colonic adenocarcinoma
    8. Stool culture or other examination positive for enteric pathogen, including Clostridium difficile (C. diff) toxin. If positive, the patient should be treated and rescreening is allowed.
    9. Men or women with childbearing potential not willing to use adequate birth control during the study. Adequate birth control includes surgical sterilization, intrauterine device, oral contraceptive, contraceptive patch, long-acting injectable contraceptive, partner’s vasectomy, double-barrier method (condom, diaphragm with spermicide), or abstinence during study and 30 days following the last follow-up visit. Women of childbearing potential will enter the study after a negative pregnancy test.
    10. Breastfeeding
    11. Chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs) from screening through the end of the study
    12. Use of topical steroids and/or topical 5-aminosalicylic acid preparations within 2 weeks before the screening visit (all such medications should be withdrawn at least 2 weeks prior to the screening visit)
